ANTON BECKER, 0F COLIVIBUS, OHIO,l ASSIGNOR TO THE RALSTON STEEL CAR COMPANY, OF COLUMBUS, OHIO, A CORPORATION OF OHIO.

yFLOOR-SUPPORT AND BOLSTER FOR HOPPER-CARS.

Specification of Letters Patent.

Patented June 11, 1912.

Application led January 30, 1909. Serial No. 475,257.

To alt whom it may concern Be it known that I, ANTON BECKER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Floor-Supports and Bolsters for Hopper-Cars, of which the following is a specification.

My invention relates to improvements in car under-frames for hopper cars and especially includes means for supporting the slope or floor sheets of the hopper from the bolster.

The invention comprises primarily the use of an angle or flanged member positioned upon and secured to the bolster diaphragms at its ends, and extending upwardly and engaging the bottom of the floor sheets, somewhat after the fashion of an arch. This construction furnishes adequate support for the floor sheets, dispenses with the use of a multitude of rivets and requires much less material than is needed for the usual construction of support-ing means at the bolster for this purpose.

The invention further includes the use of bracing and supporting means for the sides of the floor sheet preferably arranged vertically and associated with the bracing structure above described and with the bolster diaphragms.

The invention further comprises the use of a transverse member having an inclined flange thereon to engage the floor sheets, to the vertical flange or portion of which the arch-like member and the vertical member above described are applied.

The invention comprises the features before mentioned and others, and their combinations which will be hereinafter speciiically set forth.

In the drawings which are hereto attached and hereby made a part of this specification, Figure 1 is a vertical transverse section through a car provided with my improvements, the section being taken just at the rear of the bolster; Fig. 2 is a plan view of an end of the car showing the bolster construction to which my improvements above mentioned are adapted to be applied; Fig. 3 is a sectional side view of an end of a car having my improvements applied thereto.

In the drawings, 1 indicates the center sill formed in the construction here shown provided with the opening' 6 arranged for the insertion of t-he king pin.

0n each side of the center sill and applied thereto by means of rivets passing through the center sill and through the center brace, are bolster diaphragms 7 and S; the bolster may be formed of a single diaphragm on one side of the center sill or a, pair arranged on one side, both .forms being well known, and either one being adapted for use with my improvements. Underlying the center sill and the bolster diaphragms and extending from side to side of the car is a compression member 9 riveted at 10 tothe lower iiange of the bolster diaphragms. A tension member 1l overlies the center sill transversely and is secured by rivets 12 to the center sill and the upper flange of the bolster diaphragms. Sub side sills are shown at 13 and lil, and side stakes 15 and 16 are secured thereto by rivets as shown at- 17 and 13.

An angle member 19 is provided with an inclined flange 20, and this flange is applied transversely from side to side of the car to the floor sheets 21, and secured thereto preferably by riveting. A supporting member 22 is seat-ed at its ends 23 and 24: upon the upper flanges 25 and 26 of the bolster' diaphragms 7 and 8, and is riveted thereto at 27 and 28 through its lateral flange 29; this supporting member is preferably bent upwardly from its seat on the bolster diaphragms to form the sloping or inclined portions 30 and 31, the upper portion 32 lying preferably in a horizontal plane and being secured through its vertical flange to the depending flange 33 on the transverse angle member 19. The supporting member 22 is thereby securely connected with the transverse member secured to the floor sheets, and a supporting 'construction is thereby provided for the floor. The upper portion 32 of the supporting member 22 may be longer or shorter as desired, it being perceived that the general construction of this supporting member is that 0f an arch, with sufficient engagement with the flanged member depending from the Hoor sheets to form a substantial supporting conto the vertical flange of the supporting member Q2. Where two bolster diaphragms are used on each side of the center sill, I preferably employ two of the supporting members 22, and in that case fit the gusset angles 34 and 35 between the diaphragms and the supporting members, securing the same to both. Fig. 3 shows in vertical cross section a construction oi' bolster and supporting member of this kind, the position of the gusset plate 35 being shown in Fig. 2.

The advantages of my improvement conl sist in dispensing with `many rivets and thereby much labor, a saving of material, providing a construction which supports somewhat on the arch principle, and securely tying together all of the members at the bolster and iioor sheets and at the sides of the car and at the lower sides of the bolster diaphragms in such manner that all the stresses incident to the use of the car i are efficiently absorbed, and loosening and twisting of members is effectively obviated.

I do not desire to be confined to the speciiic constructions disclosed and described, but wish to take advantage of any constructions which lie within the scope of the appended claims.

What I claim is:

l. In a hopper car, a bolster, a floor supporting member mounted thereon, a sub side sill, and a gusset member secured to said loor supporting member and bolster and sub side sill.

2. In a hopper car having a bolster and floor, a member secured transversely upon the under face of said floor, a supporting member having its ends applied to the upper face of said bolster on opposite sides of the center sill, and having its middle portion bent upwardly into engagement with said transverse member, and a gusset member arranged vertically at the side of the car and secured in engagement with said transverse member, supporting member, and bolster.

3. In a hopper car, a bolster, a floor supporting member `mounted thereon7 a sub side sill, and a gusset member secured to said floor and floor supporting member and bolster and sub side sill.
